I have a server on my Network with 2 nic cards. The ip address on nic1 = 192.168.0.1 and nic2 = 192.168.0.2. I changed the ip address on nic2 to 192.168.21.1 to cnnect to the vlan for our SAN. For some reason my clients are still seeing this server as 192.168.0.2. If I flush the DNS cache on the clients, it will see the server as 192.168.0.1 but after 20 minutes my clients loses connection to the server. If I ping the server from the clients it shows ip address 192.168.0.2. When I run nslookup on my server it shows both 192.168.0.1 & 192.168.0.2. I’ve checked my DNS servers and it has been updated but why is nslookup still showing 192.168.0.2 and my clients still sees the server as 192.168.0.2? Does this seem like a DNS Server issue? I’ve looked at my forward and reverse zones and it has been updated.
Any advice?
